No. 8,385,946, issued Feb. 26, 2013, whichclaims the benefit of U.S. Provisional Patent Application Ser. No.60/946,837 filed Jun. 28, 2007, and entitled “DISFAVORED ROUTEPROGRESSIONS OR LOCATIONS”. The disclosures of the prior applicationsare considered part of (and are incorporated by reference in) thedisclosure of this application.

BACKGROUND

This disclosure relates to navigation using a mobile device.

Navigation systems have begun to include functionality for inclusion oftraffic data overlaying a navigation interface. Such navigation systems,however, provide little intelligence other than the ability to navigatefrom an origination point to a destination point. Because a user oftenhas some intelligence about routes to a location, in many instances theuser ignores navigation routes provided by the navigation system infavor of the routes the user knows. Additionally, current navigationsystems do not readily facilitate navigation to a destination if a userdesires to travel a different route while enroute on the routerecommended by the navigation system.

SUMMARY

In one aspect, systems, methods, apparatuses and computer programproducts are provided. In one aspect, methods are disclosed, whichcomprise: receiving a preference comprising disfavored routeprogressions or disfavored locations associated with a user; identifyingdestination information associated with a user; identifying one or morepotential routes comprising a plurality of route progressions based on acurrent location and the destination information; analyzing theplurality of route progressions associated with the one or morepotential routes based on the disfavored route progressions ordisfavored locations associated with the user; and presenting one ormore routes to the user based on the analysis.

Systems can include a preference engine, a destination engine, a routingengine, an analysis engine, and a presentation engine. The preferenceengine can receive disfavored route progressions or disfavored locationsassociated with a user. The routing engine can identify routes, eachroute including a plurality of route progressions. The identification ofthe routes can be based on a current location and the destinationinformation. The analysis engine can analyze the plurality of routeprogressions associated with the potential routes based upon thedisfavored route progressions or disfavored locations. The presentationengine can present preferred routes to the user, the preferred routesbeing based on results from the analysis engine

Systems and methods as described can facilitate navigation of roads bydirecting a user to use routes that do not include disfavored routeprogressions or locations associated with the user.

DETAILED DESCRIPTION

FIG. 1 is a block diagram of an example mobile device 100. The mobiledevice 100 can be, for example, a handheld computer, a personal digitalassistant, a cellular telephone, a network appliance, a camera, a smartphone, an enhanced general packet radio service (EGPRS) mobile phone, anetwork base station, a media player, a navigation device, an emaildevice, a game console, or other device or a combination of any two ormore of these data processing devices or other data processing devices.

Mobile Device Overview

In some implementations, the mobile device 100 includes atouch-sensitive display 102. The touch-sensitive display 102 canimplement liquid crystal display (LCD) technology, light emittingpolymer display (LPD) technology, or some other display technology. Thetouch-sensitive display 102 can be sensitive to haptic and/or tactilecontact with a user.

In some implementations, the touch-sensitive display 102 can comprise amulti-touch-sensitive display 102. A multi-touch-sensitive display 102can, for example, process multiple simultaneous touch points, includingprocessing data related to the pressure, degree and/or position of eachtouch point. Such processing facilitates gestures and interactions withmultiple fingers, chording, and other interactions. Othertouch-sensitive display technologies can also be used, e.g., a displayin which contact is made using a stylus or other pointing device. Someexamples of multi-touch-sensitive display technology are described inU.S. Pat. Nos. 6,323,846, 6,570,557, 6,677,932, and U.S. PatentPublication 2002/0015024A1, each of which is incorporated by referenceherein in its entirety.

In some implementations, the mobile device 100 can display one or moregraphical user interfaces on the touch-sensitive display 102 forproviding the user access to various system objects and for conveyinginformation to the user. In some implementations, the graphical userinterface can include one or more display objects 104, 106. In theexample shown, the display objects 104, 106, are graphic representationsof system objects. Some examples of system objects include devicefunctions, applications, windows, files, alerts, events, or otheridentifiable system objects.

Example Mobile Device Functionality

In some implementations, the mobile device 100 can implement multipledevice functionalities, such as a telephony device, as indicated by aphone object 110; an e-mail device, as indicated by the e-mail object112; a network data communication device, as indicated by the Web object114; a Wi-Fi base station device (not shown); and a media processingdevice, as indicated by the media player object 116. In someimplementations, particular display objects 104, e.g., the phone object110, the e-mail object 112, the Web object 114, and the media playerobject 116 can be displayed in a menu bar 118. In some implementations,device functionalities can be accessed from a top-level graphical userinterface, such as the graphical user interface illustrated in FIG. 1.Touching one of the objects 110, 112, 114 or 116 can, for example,invoke corresponding functionality.

In some implementations, the mobile device 100 can implement networkdistribution functionality. For example, the functionality can enablethe user to take the mobile device 100 and its associated network whiletraveling. In particular, the mobile device 100 can extend Internetaccess (e.g., Wi-Fi) to other wireless devices in the vicinity. Forexample, mobile device 100 can be configured as a base station for oneor more devices. As such, mobile device 100 can grant or deny networkaccess to other wireless devices.

In some implementations, upon invocation of device functionality, thegraphical user interface of the mobile device 100 changes, or isaugmented or replaced with another user interface or user interfaceelements, to facilitate user access to particular functions associatedwith the corresponding device functionality. For example, in response toa user touching the phone object 110, the graphical user interface ofthe touch-sensitive display 102 may present display objects related tovarious phone functions; likewise, touching of the email object 112 maycause the graphical user interface to present display objects related tovarious e-mail functions; touching the Web object 114 may cause thegraphical user interface to present display objects related to variousWeb-surfing functions; and touching the media player object 116 maycause the graphical user interface to present display objects related tovarious media processing functions.

In some implementations, the top-level graphical user interfaceenvironment or state of FIG. 1 can be restored by pressing a button 120located near the bottom of the mobile device 100. In someimplementations, each corresponding device functionality may havecorresponding “home” display objects displayed on the touch-sensitivedisplay 102, and the graphical user interface environment of FIG. 1 canbe restored by pressing the “home” display object.

In some implementations, the top-level graphical user interface caninclude additional display objects 106, such as a short messagingservice (SMS) object 130, a calendar object 132, a photos object 134, acamera object 136, a calculator object 138, a stocks object 140, aweather object 142, a maps object 144, a notes object 146, a clockobject 148, an address book object 150, and a settings object 152.Touching the SMS display object 130 can, for example, invoke an SMSmessaging environment and supporting functionality; likewise, eachselection of a display object 130, 132, 134, 136, 138, 140, 142, 144,146, 148, 150 and 152 can invoke a corresponding object environment andfunctionality.

Additional and/or different display objects can also be displayed in thegraphical user interface of FIG. 1. For example, if the device 100 isfunctioning as a base station for other devices, one or more“connection” objects may appear in the graphical user interface toindicate the connection. In some implementations, the display objects106 can be configured by a user, e.g., a user may specify which displayobjects 106 are displayed, and/or may download additional applicationsor other software that provides other functionalities and correspondingdisplay objects.

In some implementations, the mobile device 100 can include one or moreinput/output (I/O) devices and/or sensor devices. For example, a speaker160 and a microphone 162 can be included to facilitate voice-enabledfunctionalities, such as phone and voice mail functions. In someimplementations, a loud speaker 164 can be included to facilitatehands-free voice functionalities, such as speaker phone functions. Anaudio jack 166 can also be included for use of headphones and/or amicrophone.

In some implementations, a proximity sensor 168 can be included tofacilitate the detection of the user positioning the mobile device 100proximate to the user's ear and, in response, to disengage thetouch-sensitive display 102 to prevent accidental function invocations.In some implementations, the touch-sensitive display 102 can be turnedoff to conserve additional power when the mobile device 100 is proximateto the user's ear.

Other sensors can also be used. For example, in some implementations, anambient light sensor 170 can be utilized to facilitate adjusting thebrightness of the touch-sensitive display 102. In some implementations,an accelerometer 172 can be utilized to detect movement of the mobiledevice 100, as indicated by the directional arrow 174. Accordingly,display objects and/or media can be presented according to a detectedorientation, e.g., portrait or landscape. In some implementations, themobile device 100 may include circuitry and sensors for supporting alocation determining capability, such as that provided by the globalpositioning system (GPS) or other positioning systems (e.g., systemsusing Wi-Fi access points, television signals, cellular grids, UniformResource Locators (URLs)). In some implementations, a positioning system(e.g., a GPS receiver) can be integrated into the mobile device 100 orprovided as a separate device that can be coupled to the mobile device100 through an interface (e.g., port device 190) to provide access tolocation-based services.

The mobile device 100 can also include a camera lens and sensor 180. Insome implementations, the camera lens and sensor 180 can be located onthe back surface of the mobile device 100. The camera can capture stillimages and/or video.

The mobile device 100 can also include one or more wirelesscommunication subsystems, such as an 802.11b/g communication device 186,and/or a Bluetooth™ communication device 188. Other communicationprotocols can also be supported, including other 802.x communicationprotocols (e.g., WiMax, Wi-Fi, 3G), code division multiple access(CDMA), global system for mobile communications (GSM), Enhanced Data GSMEnvironment (EDGE), etc.

In some implementations, a port device 190, e.g., a Universal Serial Bus(USB) port, or a docking port, or some other wired port connection, canbe included. The port device 190 can, for example, be utilized toestablish a wired connection to other computing devices, such as othercommunication devices 100, network access devices, a personal computer,a printer, or other processing devices capable of receiving and/ortransmitting data. In some implementations, the port device 190 allowsthe mobile device 100 to synchronize with a host device using one ormore protocols, such as, for example, the TCP/IP, HTTP, UDP and anyother known protocol. In some implementations, a TCP/IP over USBprotocol can be used.

Network Operating Environment

FIG. 2 is a block diagram of an example network operating environment200 for the mobile device 100 of FIG. 1. The mobile device 100 of FIG. 1can, for example, communicate over one or more wired and/or wirelessnetworks 210 in data communication. For example, a wireless network 212,e.g., a cellular network, can communicate with a wide area network (WAN)214, such as the Internet, by use of a gateway 216. Likewise, an accesspoint 218, such as an 802.11g wireless access point device, can providecommunication access to the wide area network 214. In someimplementations, both voice and data communications can be establishedover the wireless network 212 and the access point 218. For example, themobile device 100 a can place and receive phone calls (e.g., using VoIPprotocols), send and receive e-mail messages (e.g., using POP3protocol), and retrieve electronic documents and/or streams, such as webpages, photographs, and videos, over the wireless network 212, gateway216, and wide area network 214 (e.g., using TCP/IP or UDP protocols).Likewise, the mobile device 100 b can place and receive phone calls,send and receive e-mail messages, and retrieve electronic documents overthe access point 218 and the wide area network 214. In someimplementations, the mobile device 100 can be physically connected tothe access point 218 using one or more cables and the access point 218can be a personal computer. In this configuration, the mobile device 100can be referred to as a “tethered” device.

The mobile devices 100 a and 100 b can also establish communications byother means. For example, the wireless device 100 a can communicate withother wireless devices, e.g., other wireless devices 100, cell phones,etc., over the wireless network 212. Likewise, the mobile devices 100 aand 100 b can establish peer-to-peer communications 220, e.g., apersonal area network, by use of one or more communication subsystems,such as the Bluetooth™ communication device 188 shown in FIG. 1. Othercommunication protocols and topologies can also be implemented.

The mobile device 100 can, for example, communicate with one or moreservices 230, 240, 250, and 260 and/or one or more content publishers270 over the one or more wired and/or wireless networks 210. Forexample, a navigation service 230 can provide navigation information,e.g., map information, location information, route information, andother information, to the mobile device 100. In the example shown, auser of the mobile device 100 b has invoked a map functionality, e.g.,by pressing the maps object 144 on the top-level graphical userinterface shown in FIG. 1, and has requested and received a map for thelocation “1 Infinite Loop, Cupertino, Calif.”

A messaging service 240 can, for example, provide e-mail and/or othermessaging services. A media service 250 can, for example, provide accessto media files, such as song files, movie files, video clips, and othermedia data. One or more other services 260 can also be utilized by themobile device 100.

The mobile device 100 can also access other data and content over theone or more wired and/or wireless networks 210. For example, contentpublishers 270, such as news sites, RSS feeds, web sites, blogs, socialnetworking sites, developer networks, etc., can be accessed by themobile device 100. Such access can be provided by invocation of a webbrowsing function or application (e.g., a browser) in response to a usertouching the Web object 114.

Example Mobile Device Architecture

FIG. 3 is a block diagram 300 of an example implementation of the mobiledevice 100 of FIG. 1. The mobile device 100 can include a memoryinterface 302, one or more data processors, image processors and/orcentral processing units 304, and a peripherals interface 306. Thememory interface 302, the one or more processors 304 and/or theperipherals interface 306 can be separate components or can beintegrated in one or more integrated circuits. The various components inthe mobile device 100 can be coupled by one or more communication busesor signal lines.

Sensors, devices and subsystems can be coupled to the peripheralsinterface 306 to facilitate multiple functionalities. For example, amotion sensor 310, a light sensor 312, and a proximity sensor 314 can becoupled to the peripherals interface 306 to facilitate the orientation,lighting and proximity functions described with respect to FIG. 1. Othersensors 316 can also be connected to the peripherals interface 306, suchas a positioning system (e.g., GPS receiver), a temperature sensor, abiometric sensor, or other sensing device, to facilitate relatedfunctionalities.

In some implementations, the mobile device can receive positioninginformation from a positioning system 318. The positioning system 318,in various implementations, can be located on the mobile device, or canbe coupled to the mobile device (e.g., using a wired connection or awireless connection). In some implementations, the positioning system318 can include a global positioning system (GPS) receiver and apositioning engine operable to derive positioning information fromreceived GPS satellite signals. In other implementations, thepositioning system 318 can include a compass and an accelerometer, aswell as a positioning engine operable to derive positioning informationbased on dead reckoning techniques. In still further implementations,the positioning system 318 can use wireless signals (e.g., cellularsignals, IEEE 802.11 signals, etc) to determine location informationassociated with the mobile device, such as those provided by SkyhookWireless, Inc. of Boston, Mass. Hybrid positioning systems using acombination of satellite and television signals, such as those providedby Rosum Corporation of Mountain View, Calif., can also be used. Otherpositioning systems are possible.

A camera subsystem 320 and an optical sensor 322, e.g., a chargedcoupled device (CCD) or a complementary metal-oxide semiconductor (CMOS)optical sensor, can be utilized to facilitate camera functions, such asrecording photographs and video clips.

Communication functions can be facilitated through one or more wirelesscommunication subsystems 324, which can include radio frequencyreceivers and transmitters and/or optical (e.g., infrared) receivers andtransmitters. The specific design and implementation of thecommunication subsystem 324 can depend on the communication network(s)over which the mobile device 100 is intended to operate. For example, amobile device 100 may include communication subsystems 324 designed tooperate over a GSM network, a GPRS network, an EDGE network, a Wi-Fi orWiMax network, and a Bluetooth™ network. In particular, the wirelesscommunication subsystems 324 may include hosting protocols such that thedevice 100 may be configured as a base station for other wirelessdevices.

An audio subsystem 326 can be coupled to a speaker 328 and a microphone330 to facilitate voice-enabled functions, such as voice recognition,voice replication, digital recording, and telephony functions.

The I/O subsystem 340 can include a touch screen controller 342 and/orother input controller(s) 344. The touch-screen controller 342 can becoupled to a touch screen 346. The touch screen 346 and touch screencontroller 342 can, for example, detect contact and movement or breakthereof using any of a plurality of touch sensitivity technologies,including but not limited to capacitive, resistive, infrared, andsurface acoustic wave technologies, as well as other proximity sensorarrays or other elements for determining one or more points of contactwith the touch screen 346.

The other input controller(s) 344 can be coupled to other input/controldevices 348, such as one or more buttons, rocker switches, thumb-wheel,infrared port, USB port, and/or a pointer device such as a stylus. Theone or more buttons (not shown) can include an up/down button for volumecontrol of the speaker 328 and/or the microphone 330.

In one implementation, a pressing of the button for a first duration maydisengage a lock of the touch screen 346; and a pressing of the buttonfor a second duration that is longer than the first duration may turnpower to the mobile device 100 on or off. The user may be able tocustomize a functionality of one or more of the buttons. The touchscreen 346 can, for example, also be used to implement virtual or softbuttons and/or a keyboard.

In some implementations, the mobile device 100 can present recordedaudio and/or video files, such as MP3, AAC, and MPEG files. In someimplementations, the mobile device 100 can include the functionality ofan MP3 player, such as an iPod™. The mobile device 100 may, therefore,include a 36-pin connector that is compatible with the iPod. Otherinput/output and control devices can also be used.

The memory interface 302 can be coupled to memory 350. The memory 350can include high-speed random access memory and/or non-volatile memory,such as one or more magnetic disk storage devices, one or more opticalstorage devices, and/or flash memory (e.g., NAND, NOR). The memory 350can store an operating system 352, such as Darwin, RTXC, LINUX, UNIX, OSX, WINDOWS, or an embedded operating system such as VxWorks. Theoperating system 352 may include instructions for handling basic systemservices and for performing hardware dependent tasks. In someimplementations, the operating system 352 can be a kernel (e.g., UNIXkernel).

The memory 350 may also store communication instructions 354 tofacilitate communicating with one or more additional devices, one ormore computers and/or one or more servers. The memory 350 may includegraphical user interface instructions 356 to facilitate graphic userinterface processing; sensor processing instructions 358 to facilitatesensor-related processing and functions; phone instructions 360 tofacilitate phone-related processes and functions; electronic messaginginstructions 362 to facilitate electronic-messaging related processesand functions; web browsing instructions 364 to facilitate webbrowsing-related processes and functions; media processing instructions366 to facilitate media processing-related processes and functions;GPS/Navigation instructions 368 to facilitate GPS and navigation-relatedprocesses and instructions; camera instructions 370 to facilitatecamera-related processes and functions; and/or other softwareinstructions 372 to facilitate other processes and functions.

In some implementations, the mobile device can also include routinginstructions 374. The routing instructions 374 can be used to providenavigation guidance to a user of the mobile device. In suchimplementations, the routing instructions 374 can provide intelligentrouting based on disfavored routes/locations, traffic, user preferences,and/or history.

Each of the above identified instructions and applications cancorrespond to a set of instructions for performing one or more functionsdescribed above. These instructions need not be implemented as separatesoftware programs, procedures or modules. The memory 350 can includeadditional instructions or fewer instructions. Furthermore, variousfunctions of the mobile device 100 may be implemented in hardware and/orin software, including in one or more signal processing and/orapplication specific integrated circuits.

FIG. 4A is a block diagram illustrating an example implementation of arouting system (e.g., embodied in routing instructions stored in amemory). The system 400 can, for example receive multiple preferencesincluding disfavored route progressions and/or locations from a user ofa mobile device and arbitrate between competing preferences to providethe user with a route based on the preferences provided by the user.

In some implementations, the routing instructions, when executed, canimplement a destination engine 410, a routing engine 420, an analysisengine 430 and a presentation engine 440. In an implementation, thedestination engine 410 can receive destination information from a userinterface 450. In various implementations, the user interface caninclude a graphical user interface such as could be provided by the GUIinstructions and touch screen of FIG. 3.

In other implementations, the destination engine 410 can derivedestination information based on historical data retrieved, for example,from a historical data store 460. The destination engine 410 can parsethe historical data to derive navigation habits. For example, a usermight drive to work every day. Thus, the destination engine 410 candetermine that there is a probability that a destination associated withthe user is a workplace. In other implementations, the destinationengine 410 can use other algorithms to derive a destination, such as aMarkov chain based algorithm. In various examples, the deriveddestination can include multiple destinations. In such examples, thedestinations can include one or more waypoints along with a finaldestination. In other examples, the derived destination can also takeinto account a parking situation associated with a destination. Thus, ifa user is headed for a stadium for a sporting event, the destinationengine 410 can determine that while the stadium is the ultimatedestination, the user might be directed to a parking lot as a waypointto park his/her car before going to the stadium.

In some implementations, the destination engine 410 utilizes dateinformation, time information, calendar information, historyinformation, preference information, etc. to derive destinationinformation. Date information can include, for example, the day of theweek, holiday information, etc. For example, a user might have a historyof navigating to/from work on Monday through Friday, navigating to/froma grocery store on Sundays, navigating to a parent's house on Mother'sDay or Father's Day, etc.

In some implementations, the destination engine 410 can also use thetime information such as, e.g., the time of day to derive a destination.For example, on Monday morning, it is likely that a user is navigatingto work, on Wednesday night it is likely that the user is navigating toa softball field for a regularly scheduled game, etc.

In some implementations, the destination engine 410 can use calendarinformation such as appointments, tasks, etc. to derive destinationinformation. For example, a user might have a calendar entry indicatinga court date on Aug. 23, 2007 at 9:00 AM, and thus it is likely that onAug. 23, 2007 at 8:30 am, the user is navigating to a courthouse. Inadditional implementations, the device can pull calendar informationfrom a variety of sources. For example, a user might keep a businesscalendar and a personal calendar on separate systems. The device canpull information from both systems to derive a destination. In otherexamples, a husband and wife might each have separate calendars and thedevice can derive destination information based upon both of thecalendars. In examples where the calendar information conflicts, thedevice can determine which calendar appointment to use, for example,based upon the current user of the device. In further examples, thecalendar information can be pulled from the local device itself, afavorite sports team calendar, a shared calendar, etc.

In some implementations, the destination engine 410 can use historyinformation to recognize patterns, and can use preference information todetermine which of a plurality of destinations the user intends (e.g., auser might indicate a preference for destination information derivedfrom calendar information over destination information derived from dateinformation). In some implementations, the destination engine 410 canautomatically recognize patterns without user input. In otherimplementations, the destination engine 410 can automatically recognizenavigation patterns and allow users to confirm or reject a destinationthrough a user interface.

In some implementations, the routing engine 420 can derive one or moreroutes based on current location information and destinationinformation. The one or more routes can be derived using existingrouting technology, e.g. map overlays. Current location information ofthe mobile device can be obtained, for example, using a positioningsystem 318. In various implementations, the positioning system 318 canbe provided by a separate device coupled to the mobile device (e.g.,mobile device 100 of FIG. 1). In other implementations, the positioningsystem 318 can be provided internal to the mobile device.

In one implementation, the positioning system 318 can be a globalpositioning system (GPS) device. In other implementations, thepositioning system 318 can be provided by an accelerometer and a compassusing dead reckoning techniques. In such implementations, the user canoccasionally reset the positioning system by marking the devicespresence at a known location (e.g., landmark, intersection, etc.). Instill further implementations, the positioning system 318 can beprovided by using wireless signal strength and one or more locations ofknown wireless signal sources to provide current location. Wirelesssignal sources can include access points and/or cellular towers. Otherpositioning systems can also be used.

The routing engine 420 can communicate one or more derived routes to ananalysis engine 430. The analysis engine 430 can analyze the one or moreroutes received from the routing engine 420. In some implementations,the one or more routes can be analyzed based on user preferencesreceived from a preference data store 470. Based on the complexity of aroute, the route can include many route progressions. Routeprogressions, in some implementations, can include discrete lengths ofroads which, when put together, make up a route.

In some implementations, the route progressions included in a route canbe analyzed based upon user preferences retrieved from a preference datastore 470. User preference data, for example, might include preferencesto avoid certain route progressions or location. In other examples, thepreference data can indicate a user preference for types of roads,distance, traffic, traffic control devices (e.g., traffic lights, stopsigns, rotaries, etc.), navigation time, preferred routes,neighborhoods, highways, restaurants, etc. In some implementations, theanalysis engine can use such preferences to select among the one or moreroutes provided by the routing engine.

In those implementations that analyze route progressions based on userpreferences, route information can be retrieved and used to provideinput by which to weight and compare routes based on the preferences. Insome implementations, route information can include disfavored routeprogressions or locations or disfavor preferences (e.g., disfavoredtypes of roads, disfavored neighborhoods, disfavor for taking the sameroute everyday, disfavored parking places (e.g., street parking, certainparking lots, etc.). In further implementations, route information canalso include a probability that a route progression will include acertain type of activity (e.g., accidents, heavy traffic) even if theroute progression is not currently exhibiting that type of activity. Inthose implementations that include disfavored route progressions orlocations or preferences, the disfavored route progressions or locationsor preferences can be avoided.

In some implementations, the routes can be analyzed based upon thetraffic information associated with route progressions included in theroute. For example, FIG. 4B is a block diagram of a plurality of routeprogressions. In the example of FIG. 4B, a first route includesprogressions A, B and X, a second route includes progressions A, C, Qand Z, and a third route includes progressions A, C and E. However,route progressions M, T, R and W are not included in any of the routesaccording to a user preference. In those implementations using trafficpreferences, the analysis engine 430 can send a request for trafficinformation associated with only route progressions A, B, C, E, Q, X andZ to the traffic information system 480, while omitting routeprogressions M, T, R and W because those route progressions are notincluded in any of the identified routes.

In other implementations using traffic preferences, the trafficinformation sent to a mobile device (e.g., mobile devices 100 of FIG. 1)can include a universe of traffic information including all availabletraffic information related to local roads. In such implementations thetraffic signal can include many component parts (e.g., one for eachavailable road), and the traffic information for the various roads canbe encoded into the signal (e.g., using time division, code division,frequency division, etc.). Thus, the analysis engine 430 can parse(e.g., decode, demultiplex, etc.) the signal to obtain trafficinformation for a desired route progression. Thus, the mobile devicemight receive traffic information associated with route progressions Athrough Z (e.g., A, B, C, E, M, R, T, W, Q, X and Z). Based on theprevious example, the analysis engine 430 can parse the trafficinformation to retrieve traffic related to route progressions A, B, C,E, Q, X and Z.

In some implementations, a user might have indicated a disfavor forroute progressions M, Q and X. A routing engine 420, for example, mighthave determined three routes associated with an origin and destination.A first route might include route progressions A, B and X, a secondroute might include route progressions A, C, Q and Z, and a third routemight include route progressions A, C and E. Based upon the exampledisfavored routes, the analysis engine 430 can remove the first andsecond routes from the potential routes, and present only the thirdroute to the user through the presentation engine 440.

In other implementations, the presentation engine can reorder thepresentation of all three routes based upon the analysis engine 430results. Routes including disfavored route progressions can be listedafter those routes that do not include disfavored route progressions. Inthose implementations including a degree of disfavor or weightingassociated with the disfavored route progressions or locations orpreferences, those routes including the most heavily disfavored routeprogressions or locations or preferences can be listed after thoseroutes including less disfavored ones. In other implementations, agraphical representation of disfavor can be applied to presented routes.For example, a color spectrum might be applied to the routepresentation, whereby green is used to depict most favorable routes,while red is used to depict most disfavored routes.

In some examples, routes might include more than one disfavored routeprogression or location. In some implementations, the route with themost heavily disfavored route progression or location can be listedafter each of the other routes. In other implementations, the analysisengine 430 can derive an aggregation of disfavor associated with theentire route. For example, a first route might include a routeprogression rated 2 (e.g., on a scale from 1 to 10, “1” being mostdisfavored and “10” being slightly disfavored), while a second routemight include several route progressions rated 3. In suchimplementations, the analysis engine can place the second route lower inpriority because the second route can be inferred to produce more totaldisfavor based upon the traversal of several disfavored routeprogressions, while the first route only includes a single disfavoredroute progression. However, as mentioned above, in some implementations,the second route can be listed ahead of the first route based on thefact that the lowest route progression rating associated with the secondroute is “3,” while the lowest route progression rating associated withthe first route is “2.”

In further implementations, a distance associated with a routeprogression can be factored into the determination of whether to givepriority to the first route or the second route. For example, if theroute progression rated “2” associated with the first route in the aboveexample were the same total distance as an aggregation of the severalroute progressions rated “3” associated with the second route in theabove example, the second route could be given priority over the firstroute. In such an example, an aggregation of the disfavor associatedwith the first route would rank the first route lower than anaggregation of the disfavor associated with the second route.

In some implementations, the route information can include historicaldata. For example, historical data can include information about theaverage time associated with navigating a route progression. The averagetime associated with each of the route progressions that are included ina route can combined to provide an estimated total time to navigate theroute. The route may then be compared to similarly analyzed routes basedon estimated total time to navigate the other routes, which can be usedto recommend a route to a user.

In some implementations, the average time to navigate a routeprogression can be dependent upon the time of day the route progressionis being navigated. For example, a section of highway in a large citymay be slow at 8:00 am due to rush hour, while the same section ofhighway might be clear at 10:00 pm. Thus, the historical data caninclude a time of day for which the average is to be computed. Forexample, the analysis engine 430 can average the five navigations takenat the closest times of day to a current time. In furtherimplementations, recency of a navigation can be factored in to theestimation of navigation time. For example, the five most recentnavigations of a road may be used to calculate an estimated navigationtime associated with the route progression. In other implementations,any of these factors can be combined. For example, the time of day canbe balanced with the recency of a navigation to produce the five mostrecent navigations which are closest in time of day to a current time ofday.

In further implementations, the route information can include mapinformation received from map system 490. In these implementations, themap information can include distances associated with routeprogressions, traffic control devices associated with route progressionsor portions of route progressions, speed limits associated with routeprogressions, etc. In some implementations, preferences can be providedwhich use map information as comparison points between potential routes.For example, if the user indicates a preference for neighborhood drivingversus highway driving, the map information can be used to reorder thepotential routes based upon such a user preference. The map informationcan therefore be used to weigh and compare routes based on thepreferences.

The analysis engine 430 can provide one or more recommended routes to apresentation engine 440 based on user preferences from the preferencesstore 470. The presentation engine 440 can communicate with a map system490 to retrieve map information. In some implementations, the map system490 can be provided, for example, by a navigation service (e.g.,navigation service 230 of FIG. 2). In other implementations, the mapsystem 490 can be provided by a map store residing on the mobile device(e.g., mobile device 100 of FIG. 1). The presentation engine 440 usesmap information provided by the map system 490 to overlay therecommended route information based on user preferences. In exampleswhere multiple routes are provided to the user, the presentation engine440 can receive a route preference from the user and display thepreferred route.

In some implementations, the routing engine 420 can continue to analyzea current route to monitor for changing conditions. For example, anaccident between the start of navigation of a route and the end ofnavigation of the route can change the analysis associated with therecommendation of the current route. In such situations, the routingengine 420 and analysis engine 430 can calculate estimated navigationtimes associated with alternative routes. In some implementations, therouting engine 420 and the analysis engine 430 can automaticallycommunicate a new route to the user through the presentation engine 440.Such automatic rerouting can be provided to the user with notificationof the change or without notification of the change to the user. Inother implementations, the routing engine 420 and analysis engine 430can present the estimated navigation times associated with alternativeroutes to the user through the presentation engine 440. The user canthen choose an alternative route based upon the estimated navigationtimes. The user's choice, in various implementations, can be indicatedby selecting a route using an I/O device (e.g., touch screen 346 of FIG.3), or by navigating one of the alternative routes, among others.

FIG. 5 is a block diagram illustrating an example implementation of apreferences engine 376. The preferences engine 376 can receivepreferences from a user through a user interface 450. The preferencesengine 376 can be configured to receive preferences on a variety ofdifferent topics. In various implementations, the preferences engine 376can be configured to receive preferences regarding disfavored routes orlocations 500 and other preferences 510.

A disfavored routes or locations preference 500 can include a user'spreferences with respect to the user's desire to avoid certain routes orcities. In some implementations, desire to avoid certain routes orlocations can be rated on a non-binary scale. In some implementations,the user preference can include a strength associated with the trafficpreferences 500. The strength, for example, could be a metric of howstrongly a user holds a preference (e.g., on a scale from 1 to 10, howstrongly they feel). In some implementations, disfavored routes orlocations can include those routes or locations to which the user hasnegative preferences. For example, a user might be afraid of heights,and therefore wants to avoid route progressions that include highbridges (e.g., the Golden Gate Bridge in San Francisco, Calif.). Inother examples, the user might want to avoid urban areas (e.g., largecities).

In some implementations, the user can provide input to the preferencesengine 376 specifying those routes or areas that the user wants toavoid. For example, the user can use a user interface to enter locationsor streets that the user wants to avoid. In some implementations, theuser can provide input to the preferences engine based upon his or heradherence to a presented route. For example, if a user consistentlydeviates from a presented route at a certain location or routeprogression, the preferences engine can use this information as inputspecifying a disfavor with a route progression or location. In otherimplementations, the preferences engine 376 can analyze historical routeinformation to identify routes or locations avoided by the user. Forexample, a preferences engine can analyze frequency of use associatedwith a street or location to determine which streets or locations a usertends to avoid.

In further implementations, a weighting can be applied to a disfavoredroute progression or location 500 based upon the extent to which a usergoes to avoid a route or location. In some implementations, thepreferences engine 376 can associate a route progression or locationthat has never been visited with a neutral rating, inferring that theuser might not be familiar with the route progression or location ratherthan consciously avoiding the route progression or location. In theseimplementations, the preferences engine 376 can infer that a routeprogression or location visited only a few times in association with acommonly traveled route is disfavored. Such an inference can be basedupon the ratio of the number of times the route has been traveled andnot included the route progression. In other implementations, a disfavorpreference 500 can be associated with route progressions or locationsnever visited.

By way of example, if a route from a first location to a second locationhas been traveled a hundred times, and included a third location only 4times, an inference can be made that the user disfavors the thirdlocation. However, if for example, the route from the first location tothe second location had only been traveled ten times, and included thethird location four times, the third location is likely not disfavored.In some implementations a weighting associated with the disfavor of aroute progression or location 500 can be set based upon the ratiobetween usage of a routes progressions/locations during a route and thetotal number of times the route has been traversed (e.g., excludingroute progressions/locations that have never been used/visited).

In still further implementations, routing instructions (e.g., routinginstructions 374 of FIG. 4A) can identify when a user avoids a routeprogression presented by the routing instructions and notify thepreferences engine 376. In such implementations, the preferences engine376 can infer from the user's rejection of the route progression thatthe user does not favor the route progression or location includedwithin the route provided by the routing instructions. In thoseimplementations including a weighting associated with a disfavored routeprogression or location 500, the preference engine 376 can infer thatthe avoidance of a route progression or location during presentation ofa route is an indication that the route progression or location shouldbe more heavily disfavored in comparison to other derivations ofdisfavored route progressions or locations 500.

Other preferences 510 can include many different types of preferencesincluding: traffic preferences, road preferences, scenery preferences,traffic control device preferences, services preferences, citypreferences, or speed preferences, new route preferences, among manyothers.

In those implementations including a strength associated with a userpreference, the analysis engine (e.g., analysis engine 430 of FIG. 4A)can use the strength to weight the route progressions and use theweighted route progressions to compare routes. For example, the user'sdesire to avoid traffic can be rated on a scale from 1 to 10, with arating of “1” corresponding to a highly disfavored route progression orlocation, and a rating of “10” corresponding to a slightly disfavoredroute progression or location. In examples where the user indicates astrong disfavor for a route progression or location, the analysis enginecan weight the route progressions with higher disfavor more negativelythan those with slight disfavor, thereby making it more likely that ananalysis engine (e.g., analysis engine 430) will recommend routes havingslight disfavor or no disfavor at all. However, in the implementationsthat include multiple preferences associated with the user, thestrengths of other preferences could outweigh other preferencesdepending on a strength associated with the other preferences.

In some implementations, a group of users can rate a route progressionin several categories. The route progression can be assigned a scorebased on the user ratings. In other implementations, route progressionscan be assigned scores based on the individual route progression'spopularity among users that have indicated a strong preference for acertain kind of route progression. For example, if a user or group ofusers indicate a strong preference for scenic roads, and each uses acertain road more frequently in comparison to other roads, the systemcan assign a high scenery score to the road. In still furtherimplementations, the route progressions can be rated automatically basedon measurable statistics. For example, traffic information can identifywhich route progression is the worst for traffic based upon the averagespeed associated with the road, or based upon a delta between averagespeed and speed limit. Similarly, the best route progression for trafficcan be identified based on the average speed associated with the road,or based upon a delta between average speed and the speed limit. Theworst route progression can be assigned the lowest possible score, andthe best route progression can be assigned the highest possible score,while other route progressions are assigned scores which are scaledbased upon the high and low scales. Such automatic scoring can beperformed where there is an objective measure by which to compare routeprogressions.

FIG. 6 is a flowchart illustrating an example method for route guidance.At stage 600 disfavored route progressions or locations or preferencesare received. Disfavored route progressions or locations can bereceived, for example, by a preferences engine (e.g., preferences engine376 of FIG. 5) in conjunction with a user interface (e.g., userinterface 450 of FIG. 5). The disfavored route progressions or locationscan include, for example, any route progressions or locations indicatedby the user (e.g., through a user interface, frequency of use, avoidanceof presented routes, etc.).

At stage 610 the destination is identified. The destination can beidentified, for example, by a destination engine (e.g., destinationengine 410 of FIG. 4). In some implementations, the destination enginecan identify destination information from user input received using auser interface (e.g., user interface 450 of FIG. 4). In suchimplementations, the user can provide destination information to amobile device (e.g., mobile device 100 of FIG. 1). In otherimplementations, the destination engine can identify destinationinformation based on historical data retrieved from a history data store(e.g., history data store 460 of FIG. 4). For example, the destinationengine can mine the historical data to automatically derive navigationpatterns based on such variables as day, time of day, holiday, and usercalendar, among many others. In still further examples, the destinationengine can identify destination information based on a combination ofuser input and historical information. For example, the destinationengine can use the user interface to prompt the user to select adestination from among a group of destinations derived based on thehistorical data.

At stage 620, routes associated with the destination are identified. Theroutes can be identified, for example, using a routing engine (e.g.,routing engine 420). In some implementations, the routing engine canreceive position information from a positioning system (e.g.,positioning system 318 of FIG. 4). The positioning information can beused as a starting point for the routing engine. In someimplementations, the routing engine can use a navigation service (e.g.,navigation service 230 of FIG. 2) to derive one or more routes. In otherimplementations, the routing engine can use GPS/navigation instructions368 to derive one or more routes.

At stage 630, the route is analyzed based on disfavored routeprogressions or locations or preferences. The route can be analyzed, forexample, using an analysis engine (e.g., analysis engine 430 of FIG. 4).The analysis can retrieve disfavored route progressions or locationsfrom a preferences store (e.g., preferences store 470 of FIG. 4) and usethe preferences to weight the route progressions included in theidentified routes. The weighted route progressions can be used torearrange the identified routes based on the user preferences. In someimplementations, the analysis can retrieve route information fromseveral different sources (e.g., history data store 460, trafficinformation system 480, map system 490, of FIG. 4) to use in conjunctionwith the preference information.

At stage 640, a route is presented. The route can be presented, forexample, by a presentation engine (e.g., presentation engine 440) to auser of a mobile device. The presented route can be overlaid onto a mapprovided by a navigation system (e.g., map system 490 of FIG. 4, ornavigation services 230 of FIG. 2). In other implementations, the routecan be overlaid on a map provided by a local map data store. In someimplementations, the map includes a number of road representations. Infurther implementations, the road representations, for example, can beoverlaid by route information associated with respective routeprogressions. The presentation of the route can enable a user of themobile device to navigate from a current position to a destination.

FIG. 7 is a flowchart illustrating another example method for routeguidance. At stage 700 user preferences are received. Preferences can bereceived, for example, by a preferences engine (e.g., preferences engine376 of FIG. 5) in conjunction with a user interface (e.g., userinterface 450 of FIG. 5). The preferences can include, for example,disfavored route progressions or locations as well as other preferences.In various implementations, other preferences can include trafficpreferences, road preferences, scenery preferences, traffic controldevice preference, services preferences, city preferences, speedpreferences, or other preferences. Disfavored route progressions caninclude, for example, streets that the user does not want to take forsome reason (e.g., a road that is in disrepair, etc.). Disfavoredlocations can include, for example, areas that the user wants to avoid(e.g., industrial areas, areas with high traffic, etc.). In someimplementations, disfavored route progressions and/or locations can bedisfavored dependent on a time of day. For example, a user might dislikedriving on a particular road or through a particular area at night,while not disfavoring the road or area during the daytime. In furtherimplementations, there can be multiple sets of preferences, each set ofpreferences being associated with a particular user of the device. Insuch implementations, the device can provide route guidance based uponthe particular user who is logged into the system.

In some implementations, the preferences can be received directly from auser. For example, a user can use a user interface to enter his or herdisfavored roads and/or areas. In other implementations, the preferencescan be derived based upon the user's actions during previous routeguidance. For example, if a user consistently refuses to follow apresented route, the device can determine that the user disfavors theroute progression and/or location where he/she deviated from the route.In some implementations, the disfavor can be time-based. For example, auser might heavily disfavor a route progression in the morning, butfavor the route progression at night. In other implementations, thepreferences can be derived based upon historical data. For example, if auser travels from home to work every day for a year, and has used aparticular road on that trip only once, a preference engine can derivethat the user disfavors that road or area associated with the road. Insome implementations, a combination of user input, deviation from routeguidance and/or derivation from historical data can be used to determinepreferences.

At stage 710 the destination is received/identified. The destination canbe received, for example, by a destination engine (e.g., destinationengine 410 of FIG. 4). In various implementations, the destinationengine can operate based on user input received using a user interface(e.g., user interface 450 of FIG. 4), or can automatically derive adestination based on historical data, and combinations thereof.

At stage 720, routes associated with the destination are identified. Theroutes can be identified, for example, using a routing engine (e.g.,routing engine 420). In some implementations, the routing engine canreceive position information from a positioning system (e.g.,positioning system 318 of FIG. 4). The positioning information can beused as a starting point for the routing engine, and the routing enginecan use a navigation service (e.g., navigation service 230 of FIG. 2) toderive one or more routes. In other implementations, the routing enginecan use GPS/navigation instructions 368 to derive one or more routes.

At stage 730, the route is analyzed based on user preferences. The routecan be analyzed, for example, using an analysis engine (e.g., analysisengine 430 of FIG. 4) in conjunction with preference informationretrieved from a preference store (e.g., preferences store 470 of FIG.4). In some implementations, the analysis can receive several differentroutes and prioritize the routes based on the received user preferences,including, for example, disfavored route progressions and/or locations.In some implementations, the analysis engine can reorder thepresentation of a plurality of identified routes based on analysis ofthe route progressions with respect to the user preferences.

At stage 740, a route is presented. The route can be presented, forexample, by a presentation engine (e.g., presentation engine 440) to auser of a mobile device. The route can be presented in any of the waysdiscussed with reference to FIG. 6.

At stage 750, a determination can be made whether a destination has beenreached. The determination can be made, for example, by an analysisengine (e.g., analysis engine 430 of FIG. 4) in conjunction with apositioning system (e.g., positioning system 318 of FIG. 4). Where thedestination has been reached, the process ends at stage 760.

If the destination has not been reached, the method can return to stage720, where alternative routes including a plurality of routeprogressions are retrieved. The route progressions associated with thealternative routes can then be analyzed, and one or more alternativeroutes are presented to a user based on the analysis (e.g., an accident,traffic build-up, traffic clearing up, time of day dependencieselapsing, etc.). Thus, a mobile device (e.g., mobile device 100 ofFIG. 1) can reroute the user based on changing road conditions. In someimplementations, an alternative route is automatically presented to theuser without notification, and replaces the current route. In otherimplementations, a user can be notified that another route might bepreferable, and the estimated navigation times associated with bothroutes can be compared and the user can decide whether to continue on acurrent route, or to take an alternative route.
